DETAILED DESCRIPTION OF THE DRAWINGS

[0028]FIGS. 1 to 7 show an alignment adjusting device integrated in an optical focal plane assembly in different views. The optical focal plane assembly is mounted on an optics assembly which is not shown in the figures. Those elements such as thermal insulation, optical baffles, radiation shields, etc. which are not relevant for the alignment are not shown in the figures. The detector plane (image area) can be aligned with help of the alignment adjusting device described below. This alignment can be made with an accuracy of more than one micron in any direction, respectively five arcseconds around any axes of an Cartesian coordinate system.

[0029]As will be apparent from the description below, the alignment adjusting device is designed such that during the alignment process a flange 1 can remain mounted at the not shown optics assembly, i.e. without removing the connection, and without exchanging any components of the alignment adjusting device or...

Abstract

An alignment adjusting device is provided for an optical focal plane assembly, wherein the optical focal plane assembly has a detector with a detector plane and is adapted to be mounted to an optics assembly having an optical focal plane. The alignment adjusting device is adapted for allowing an alignment of the detector plane representing an image area and the optical focal plane. The alignment adjusting device includes a detector support for receiving the detector; a plurality of members, wherein a first member of the plurality of the members is connected to the detector support and a second member is connected to a flange that is adapted to be connected to the optics assembly. The first member, the second member and the remaining number of the members are pairwise moveable connected to each other by a number of springs and/or supporting elements. The number of springs and/or supporting elements are adapted to enable a translational movement along axes and/or a rotational movement around the axes of a given coordinate system.

Description

BACKGROUND AND SUMMARY OF THE INVENTION[0001]The invention relates to an alignment adjusting device for an optical focal plane assembly. The alignment adjusting device is adapted to be integrated in an optical focal plane assembly comprising a detector having a detector plane and is adapted to be mounted to an optics assembly having an optical focal plane. The alignment adjusting device is adapted for allowing an alignment of the detector plane to the focal plane of the optics assembly, i.e. the optical focal plane.[0002]Alignment adjusting devices are used for light detectors of optical instruments. The light detectors have to be adjusted with regard to the optical path micron precise. An alignment adjusting device which allows such an adjusting enables adjusting the optical focal plane assembly with regard to a predetermined length in any direction and / or around a predetermined angle around any axis. Conventional alignment methods require an exchange of precision stops or wedge ri...
